    摘要:

    通過(guò)熱力學(xué)計(jì)算，繪制了298K溫度條件下Zr-H2O系電位-pH平衡圖及升溫條件(333，373，423K)下Zr-H2O系電位-pH平衡圖。所繪制的298K溫度下Zr-H2O系電位-pH平衡圖與M．Pourbaix繪制的相同溫度條件下Zr-H2O系電位-pH平衡圖很好地吻合。比較分析不同溫度條件下Zr-H2O系電位-pH平衡圖發(fā)現(xiàn)，隨著溫度的升高，鋯金屬的免蝕區(qū)變化不大，而鈍化區(qū)則明顯縮小。從理論上說(shuō)明了鋯金屬用于高溫條件的局限性。

    Abstract:

    The Potential-pH diagrams of the Zr-H2O system at temperatures of 298 K, 333 K, 373 K and 423 K were be established through extensive study of thermodynamic data and thermodynamic calculation coupled with experimental results? The Potential-pH diagram at 298 K concides with that at the same temperature drawn by Professor M.Pourbaix. Comparing and analyzing potential-pH diagrams of Zr-H2O system at different temperatures, it is evident that with the temperature increasing there is no great change of the immunity area of zirconium, but remarkable reduction of the passivation area, which theoretically accounts for the high temperature limitation of zirconium.
